NON-RSEFILLABLE BOTTLE.

SPECIFICATION forming part ofLetters Patent No. 593,825, dated November 16, 1897.

Application filed September 29, 1896. Serial No. 607,312. (No model.) I

To aZZ whom it may concern:

Be it known that we, ALBERT B. WILSON and EDWIN E. OHATFIELD, citizens of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful .Improvements in Non-Refillable Bottles; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, and to letters of reference marked thereon, which forms a part of this specification.

The objects of this invention are to simplify and cheapen the construction of nonrefillable bottles, to more effectually prevent the refilling of bottles with liquids of inferior quality, and to secure other advantages and results, some of which may be referred to hereinafter in connection with the description of thedevice.

The invention consists in the improved non-refillable bottle and in the arrangements and combinations of parts, all substantially as will be hereinafter set forth, and finally embraced in the clauses of the claim.

Referring to the accompanying drawing and the letters of reference marked thereon,

vsaid drawing being a central vertical section of the bottle, a indicates the body of the bottle, the head a of which is provided at a point immediately above the neck a with a shoulder 1), formed by enlarging the neck horizontally. The shoulder 19 is made flatand presents a broad seat-surface, against which the correspondingly flat valve rests. Said head above the shoulder is bent inward annularly, as at c, to form a guard, and above the guard the said head is provided with a main mouth 0', through which the fluid to be contained in the bottle is introduced. At one side of the upper portion of the head the same is provided with a supplemental outflow-opening e, through which the fluid flows outward in emptying the bottle. We may also provide at a point preferably opposite the said outflow passage or opening a vent-opening f to facilitate the pouring out of the contents. At the main mouth or supply-opening 't' the head is provided interiorly with a shoulder g, on

which a packing or washer it may be seated, and on said washer is secured a plug or stopper vi, the upper flange j of which closely fits within themouth and is held in place by cement or other suitable material adapted to produce an impervious joint. Said plug or stopper at its lower part also provides a guard, flange, or foot 70, which lies a little below the plane of the annular guard c and above the shoulder 12, cooperating'with said part c ,to prevent interference with the valve Z, which cuts off inflow to the bottle to prevent refilling. The said flat valve Z comprises a disk of glass centrally perforated and smoothly hugging or engaging at and near its periphery the shoulder 12, the said disk being preferably ground upon the said shoulder, so that when the parts are wet with the contents of the bottle or with fluid to be introduced thereto in an attempt at refilling the said disk will be held in impervious relation to the shoulder by atmospheric pressure on principles well understood in connection with thesuckers commonly used by boys as toys.

Through the perforation Z of the disk valve we insert a silk cord or thread m, to the lower end of which is attached a globule n, which latter tends to draw the valve to its closed position when the bottle is turned upright, and also to open the said valve by force of impact when the said ball is allowed to drop against the under side of the disk when reversing the position of the bottle.

The suction produced by the engaging flat and wet surfaces is sufficient to hold the valve closed upon itsseat even when the bottle is reversed and the weight of the contents is brought to bear thereon, but by the sharp hammer-like blow of the glass ball upon the glass valve this suction is broken and the valve will then open. A sufficient suction cannot be obtained by a ball-valve engaging a shoulder of a different shape, so that the ball engages the shoulder in an annular line only, as will be apparent.

To secure the advantageous results desired, we employ a disk valve, flat where it engages the corresponding shoulder, said corresponding flat shoulder,and a weight attached to the disk by a flexible cord.

The foot It serves as a stop to limit the opening movement of the valve and prevent the said valve from falling or moving to a position from which it will not properly close when the weight draws upon the string or cord. The cord is flexible and admits of a free movement of the Weight or globule n, so that the latter will not serve in opening the valve except when the bottle is turned mouth downward.

In operating the device the fluid is first introduced through the main opening before the valve and stopper are placed in position. The main mouth of the bottle is then closed by the plug or stopper and the latter cemented and sealed by wax in any suitable manner. The vent-hole and outflow-opening are also closed by cork or other equivalent closing means. When it is desired to open the bottle, the stopper is removed from the venthole and outflow-openings and the bottle turned bottom up, when the weight of the fluid will force open the valve, or should said valve stick fast because of gummy substances in the fluid or because of the air-pressure above referred to the weight will serve as a hammer to force open said valve, and the fluid is thus allowed to escape.

When the empty bottle is in a position for refilling, such refilling will be prevented by the valve, and because of the suction or air-pressure upon the disk as it lies on the shoulder it is found impossible to introduce the fluid in small amounts to the bottle by any shaking process, but, on the contrary, because of the said suction or air-pressure the said disk is caused to hug the shoulder, and the said disk will not open except when a positive weight is brought to bear against the under side.

Having thus described the invention, what we claim as new is The improved non-refillable bottle comprising a bottle having a flat annular shoulder formed in the neck and above said shoulder providing an outlet for the fluid and a seat for a permanent plug, of a flat disk valve centrally provided with means for securing a flexible connection, said flexible connection and a weight attached thereto, and a plug seated in said neck and having a foot or hearing 70, for limiting the movement of the disk, substantially as set forth.

In testimony that we claim the foregoing we have hereunto set our hands this 23d day of September, 1896.
